1. Haluska, Nathan. Optical Properties of Type III-V Semiconductor Spherical Quantum Dot Heterostructures.

Degree: MSin Engineering Physics, Physical Sciences, 2010, Embry-Riddle Aeronautical University

In recent years quantum dots (QD) have attracted increasing interest because of their wide variety of revolutionary applications. Such applications include high speed optical communication lasers, infrared photodetectors, and single photon emitters. One promising immediate application is QD solar cells. Proper analysis of the optical absorption characteristics in these solar cells requires a rigorous modeling of the electronic structure and optical properties of semiconductor heterostructures. Our emphasis will be on type III-V semiconductors. Such structures, have a great potential for increasing efficiencies, but they also possess highly degenerate and complex valence band structures. Therefore, we seek to develop a model of spherical QD band structure for type III-V Semiconductor materials, and with such results we obtain the absorption properties of the simulated QDs. We assume stress and strain effects are negligible. We also assume the conduction and spin-orbit bands are treated as distant. We utilize the spherically symmetric, single and multiple band effective mass equations along with previously developed analytical methods to simplify the problem, then we obtain the eigenfunctions and eigenenergies of the QD, and use them to model optical transitions. We assume a quasi-equilibrium Fermi-Dirac distribution for electrons and holes and obtain the microscopic transition rates and absorption coefficients. Furthermore, we implement this in Matlab with a robust graphical user interface which allows for arbitrary configurations of materials and QD sizes. With this tool, the eigenenergies, eigenfunctions, and absorption coefficients may be calculated. Advisors/Committee Members: Dr. Bereket H. Berhane, Dr. Gulamabas Sivjee, Dr. John Mathis.

2. Burke, Damon. Rocket Borne Measurements of a Near-Infrared Vehicle Induced Emission with a Newly Designed Spectrograph.

Degree: MSin Space Science, Physical Sciences, 2005, Embry-Riddle Aeronautical University

In order to broaden current knowledge of a particular vehicle induced atmospheric glow, a modified Ebert-Fastie Spectrograph was designed and built at Embry-Riddle Aeronautical University for rocket borne observations of this glow. This instrument became a piggy-back payload on the Terrier-Orion SAMPLER 41.025 rocket payload launched from White Sands Missile Range in July, 2003. A photodiode detector array measured the mesospheric hydroxyl airglow emissions during the initial ascent as well as the vehicle induced glow through the mesopause at eight discreet bandpasses. Data collected shows moderate agreement with previous measurements by Murtagh et al. [1997] and Lopez-Moreno et al. [1985] over similar wavelengths. With this data we attempt to show some correlations between the hydroxyl airglow and the vehicle induced glow. Advisors/Committee Members: Dr. Peter Erdman, Dr. John Olivera, Dr. Gulamabas Sivjee.
